flink on native k8s jobManger频繁重启，caused by too old resource version
Hi，
flink 1.12.1 on native k8s application模式，jobManager频繁重启可能是什么原因导致的，报错日志如下：

Hi！
io.fabric8.kubernetes.client.KubernetesClientException: too old resource
version 这个问题可能是由于 Pod 和 APIServer之间的网络不稳定。这个问题已经在 1.12.2 版本被修复，详见
https://issues.apache.org/jira/browse/FLINK-20417
建议使用 Flink 1.12.x 的最新版本。
